It is not black magic, analysis is needed to the parts of OS being migrated.
And, who has the time (or the expertise) to do that analysis?
Or, do you plan on paying IBM to do it for you?
No, but I had to do it. Quite simple configuration, but out of
coexistence window.
Don't ask why.
I've even went from DB2 v4 to v6 directly. Yes, it is not supported, it
is not possible to migrate the data ...unless you do it manually:
re-define all the DB2 objects then unload and reload data. Time
consumig, requires some scripts, no method to fallback, but it worked.
It required some testing before. IMHO not too much.
Sometimes extra actions like JES2 off/re-load (or even cold start) are
sufficient for given component.
Sufficient, maybe.
But, desired?
Desired ??? Maybe required.
BTW: I still vote for 'legal' upgrades within coexistence window. I fan
of that <g>.
